True or False:  If a wet-mount of milk, water, and a small amount of ink (nigrosin) is viewed under high power with a light microscope, individual water molecules can be seen vibrating or “bouncing,” due to random thermal motion.

When a plant cell is placed in a solution of high salt concentration, the cell membrane shrinks away from the cell wall and concentrates the cellular contents.  This process, which can easily be observed using a light microscope, is called …
